Ac-L2-01b Ys-class Trawler

The Ac-L2-01b Ys-class Trawler is a large-scale fishing barge created by Ahmida Civiltech in AR 874.

About the Ship

The Ys-class is a well-performing interplanetary fishing trawler designed for the harvesting of flora and fauna from natural or artificial aquatic environments. It boasts a capacity of several dozen small shuttles and aircraft for prospecting and fishing, and numerous pisciculture tanks that allow it to keep its cargo live. In a pinch, it can also be used to carry a bulk cargo of clean water for commerce.

Key Features

  • Large cargo capacity.
  • Carries repurposed Quodr for field operations.
  • Pisciculture tanks.
  • Able to submerge and float on water.

Mission Specialization

  • Fishing and food production.
  • Water transport.
  • Exploration of aquatic planets.


Ac-L2-01b Ys-class Fishing Trawler

History and Background

The Ys was designed as part of an initiative to move pisciculture and industrial-scale fishing off-world from the ecologically fragile regions of Hlarai and Maekardan and onto artificial environments that would be better controlled and harvested. In order to properly make use of those investments, a number of large-scale fisheries commissioned Ahmida to develop fishing vessels that could sample local undersea ecologies, catch fish on a massive scale and store them effectively for transport. A secondary feature and consequence of the large-scale 'live' holding tanks is the ability to re-purpose them for fish farming, so a ship may remain profitable during moratoriums or if the owner does not wish to engage in on-site fishing operations.

Like its predecessor, the Ur, the Ys is a comfortable and functional vessel with personnel quarters that compromise on space but not on comfort. Although less produced than the Ur, the Ys has a reputation for reliability and quality. Many of the ships produced in the AR 870's are still in operation now.
